. CONNECTION FOR DRIVING-RODS.

SPECIFICATION forming part of Letters Patent No. 787,502, dated April 18, 1905.

Application filed January 12, 1905. Serial No. 240,825.

To all whom, it may concern.-

Be it known that I, BENEDICT ALoYsIUs EIDEN, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Connections for Driving-Rods; and I do declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in connections for driving-rods.

The object of the invention is to provide a boltless connection or joint for machine driving-rods, and particularly for the main and parallel connecting-rods of locomotives.

Another object of the invention is to provide an improved construction and arrangement of brasses orwear-plates whereby they may always be' kept solid and tight and may be removed from the rods without taking the same off the crank-pins.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a locomotive connectingrod constructed in accordance with the invention. Fig. 2 is a top plan view. Fig. 3 is a bottom plan View of the same. Fig. L is a longitudinal vertical sectional view, and Fig. 5 is a cross-sectional view on the line 5 5 of Fig; 1.

Referring more particularly to the drawings, 1 denotes a locomotive connecting-rod having on one end a cross-head connection 2, which is in the form of an integrally-formed bearing-strap 3,in which are arranged bearingbrasses. These brasses are held in place and adjusted by gib-bolts 5 and a wedge-shaped key 6, the gib-bolts 5 being held in place by washers 7 and nuts 8. The key 6 is held in its adjusted position by means of a set-screw 9. By this arrangement the brasses t may be adjusted to take up the wear and to hold the same into firm engagement with the pivotpin of the cross-head.

shaped adjusting-block 13, said block being adapted to be adjusted, by means of set-screws 14, to hold the brasses 11 into engagement with the crank-pin, thereby taking up the wear on the same.

Below the brasses l1 and within the strap 10 is arranged a jam-plate 15, which is adapted to be adjusted, by means of adjustingscrews 16, to hold the brasses 11 in position. In the brasses 11 is journaled a crank-pin 17, and on the outer end of the said crank-pin is formed a reduced threaded portion with which is adapted to be engaged a retaining-collar 18. Said collar 18 is held in place by means of nuts 19 and a cotter-pin 20, thus pivotally engaging the end of the connecting-rod with the crank-pin of the locomotive drive-wheel.

While I have shown and described the invention as applied to a locomotive connecting-rod, it is obvious that the same may be applied and used in connection with the parallel rods of a locomotive or in connection with any form of machine driving-rod, the object of the invention being to simplify the construction and arrangement of the connections for any form of driving-rod, whereby the same may be constructed and applied without the use of bolts, thus permitting the same to be cast instead of forged, thereby necessitating less machine-work, less bench and floor worksuch as laying out, filing, chipping, and fitting updoing away with formation of keyholes and bolt-holes and the filing and matching of parts. By this arrangement the brasses may also be kept solid and tight, thereby preventing all lost motion and saving a great deal of time in reducing the brasses, especially in connection with roundhouse-work.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The herein-described driving-rod having integrally-formed bearing-straps, brasses, a gib and key for taking up the Wear of said brasses, flanged brasses arranged in the strap at the opposite end of said rod, a wedgeshaped adjustingblock, a jam plate, setscrews arranged in said strap to adjust and hold said wedge-block and jam-plate, a crankpin collar, and means whereby the same is connected to the end of a crank-pin to hold said driving-rod in place.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

BENEDICT ALOYSIUS EIDEN.
